[Wiring Precautions]

DANGER For installation and wiring works, make sure that the power source is shut off for all outside

phases. If all phases are not turned off, it may cause an electric shock or product damages. When the input voltage of voltage transform module is 55 V or less, voltage display will be 0 V by

cut-off. The voltage maybe still applied even if the display is 0 V. Touching the active wire is strictly prohibited. Make sure shut off the switch, and check the voltage was not been applied.

A - 3

CAUTION FG terminal must be grounded according to the D-type ground (Type 3) dedicated for sequencer.

Failure to do so may result in electric shock or malfunction. When using this product, make sure to use it in combination with current sensor (EMU-CT***,

EMU-CT***-A or EMU2-CT5-4W) and Voltage transform module (QE8WH4VT). Please not to exceed the ratings of this product for input of current sensor. For further details, please refer to current sensor manual to maintain the functionality and the accuracy of this product. The available range of the voltage transform module is from 63.5/110 to 277/480V AC. When used in a circuit more than 227/480V AC, voltage transformer is required.

Current sensor (EMU-CT***, EMU-CT***-A (Excluding EMU-CT5-A)) is used only for low voltage circuit. It cannot be used with a high voltage circuit. Also, EMU2-CT5-4W and EMU-CT5-A should be used with the secondary side (5 A) of transformer transfixed. If it is connected with a high-voltage circuit by mistake, it may cause a burnout of the device and a fire. It is critically dangerous. For the Allowable maximum voltage, refer to Appendix 2 “Optional devices”.

Current sensor has a polarity (directionality). Be careful about it when installing the module. Do not open the secondary side of current sensor. Take care not entering any foreign objects such as chips and wire pieces into the module. It may cause

a fire, failure or a malfunction. In order to prevent the module from incoming foreign objects such as wire pieces during wiring work, a

foreign-object preventive label is placed on the module. While a wiring work is performed, keep the label on the module. Before operating the system, peel off the label for heat release. If the foreign-object preventive label is not peeled and the system is in use, residual heat inside the module may reduce the product life.

The wires to be connected to the module shall be put in a duct or fixed together by clamp. If not, the loosing and unstable wire or careless stretching results in poor contact of electric wires. That may cause a breakage of the module or wire or a malfunction.

After wiring, confirm whether there is a wiring forgetting or a faulty wiring. They may cause a device malfunction, a fire, or an electric shock.

When removing the wires connected to the module, do not pull wires as holding on their electric wire portions. Push the buttons on the terminal, and then remove the wire.

If the wires connected to the module are strongly pulled off, it may cause a malfunction or a breakage to the module or the wire. (Tensile load: 22 N or less)

Ensure the wiring to the module properly, checking the rated voltage and current of the product and the terminal pin assignment. If the input voltage exceed the rated voltage or the wiring is improper, it may cause a fire or a breakage.

Do not exceed the specified voltage when doing an insulation resistance test and a commercial frequency withstand voltage test.

To protect persons who do not have adequate knowledge of electric equipment from elevtric shocks, any of the following measures should be taken for the panel.

(a) To lock the panel so that only trained persons having adequate knowledge of electric equipment can open it.

(b) To design the structure so that the power is automatically interrupted upon opening of the panel. The protection class of the panel should be IP2X or higher. Terminal screws must be tightened to the specified torque. Loose terminal screws may cause a short

circuit or malfunction. If terminal screws are over-tightened, the screws or the module may be damaged, causing a short circuit or malfunction.

For specified torque, refer to Section 8.1 Precautions for handling. Use an applicable solderless terminal for the current input line and tighten it to the specified torque. If a

spade terminal is used, it may fall, causing a breakage of the module when the terminal screw is loosened.

Use appropriate size of electric wires. If inappropriate size of electric wire is used, it may cause a fire due to generated heat. For appropriate size of electric wires, refer to Section 8.5.2 How to connect wires.

In case using stranded wire, take measures so that the filament should not vary by processing the point twisted.

(4) Restrictions for measuring data

- Measurement cannot be performed immediately after the power loading to the sequencer

system (Module ready signal is under the OFF condition).

After checking that Module ready (Xn0) is ON, obtain measuring data.

- Measurement cannot be performed immediately after operating conditions are set up to the

module. After checking that Operating condition setting completion flag (Xn9) becomes ON,

obtain measuring data.

- Behaviors during operation are as follows:

Measuring item Behavior of the module

Current When the input current is less than 0.4 % of the rating current, it

becomes 0 A.

Current demand Current demand is obtained by current moving average. Therefore,

even if current is 0 A, current demand may not be 0 A.

Voltage (L-N) When the input voltage (L-N) is less than 55 V, it becomes 0 V.

If there is no input at voltage V1N, all measurement cannot be

done.

Voltage (L-L) When the input voltage (L-L) is less than 95 V, it becomes 0 V.

Electric power,

Reactive power,

Apparent power

When current is 0 A (at all phases are 0A) or when voltage is 0 V

(all phases are 0 V), it becomes 0 kW.

Electric power demand Electric power demand is obtained by electric power moving

average. Therefore, even if electric power is 0 kW, electric power

demand may not be 0 kW.

Electric energy The electric energy is measured with a load that is about 0.4 % or

more of all load power. Even if the indicated value is “0”,

measurement value will increase.

Power factor When current is 0 A (at all phases are 0 A) or when voltage is 0 V

(all phases are 0 V), it becomes 100 %.

Frequency Voltage condition

When the input voltage (L-N) is less than 55 V, it becomes 0 Hz.

Frequency condition

When it is less than 44.5 Hz, it is fixed to 44.5 Hz.

2) Setting procedures are as follows:

(a) Check that Operating condition setting request (Yn2) is OFF. (b) Set the alarm item, alarm value, alarm reset method, and alarm delay time in the buffer

memory. For the address of buffer memory for alarm 1 and alarm 2, refer to Chapter 6. (c) Set Operating condition setting request (Yn2) to ON. Operation starts at each set value,

and then Operating condition setting completion flag (Xn2) is turned ON. (d) Check that Operating condition setting completion flag (Xn2) becomes ON, and then set

Operating condition setting request (Yn2) to OFF. Operating condition setting completion flag (Xn2) will be turned OFF.

Figure 4.2.4-1 Time chart of alarm monitoring setting 3) Each item of the alarm monitoring is stored in the nonvolatile memory, so that values can be

retained even at a power source reset.

(2) Behavior of the upper/lower limit alarm

1) When the alarm reset method is set to "0: self-retention" (example of the upper limit

monitoring with CH1 alarm 1)

(a) If the measured value that was set with the alarm 1 item exceeds the upper limit and the

situation continues and remains for the alarm 1 delay time, CH1 alarm 1 flag (Xn9) will turn

ON. At the same time, ALM1 LED flashes.

(b) Even if the measured value goes below the upper limit, CH1 alarm 1 flag (Xn9) remains in

the ON status (self-retention). During the self-retention, ALM1 LED is lit.

(c) By turning CH1 alarm 1 reset request (Yn9) to ON, CH1 alarm 1 flag (Xn9) will turn OFF.

At this time, ALM1 LED is turned off.

(d) Check that CH1 alarm 1 flag (Xn9) becomes OFF, and then set CH1 alarm 1 reset request

(Yn9) to OFF.

2) When the alarm reset method is set to "1: auto reset" (example of the upper limit monitoring

with CH1 alarm 1) (a) If the measured value that was set with the alarm 1 item exceeds the upper limit and the

situation continues and remains for the alarm 1 delay time, CH1 alarm 1 flag (Xn9) will turn ON. At the same time, ALM1 LED flashes.

(b) If the measured value goes below the upper limit, CH1 alarm 1 flag (Xn9) will turn OFF. At this time, ALM1 LED is turned off.

(c) If the measured value that was set with the alarm 1 item exceeds the upper limit but goes below the upper limit within the alarm 1 delay time, then CH1 alarm 1 flag (Xn9) will remain in the OFF status.

Figure 4.2.4-3 chart of the upper/lower limit alarm (alarm reset method = “auto-reset”)

3) An example of the alarm 1 was indicated in 1) and 2) above. The alarm 2 will be in accordance with the same behavior. For the setting items for the buffer memory that corresponds to the alarm 2 and the I/O signals, refer to Chapters 5 and 6. The following describes a case with the alarm 2.

[When the alarm reset method is set to "1: auto reset" (example of the lower limit monitoring

with CH1 alarm 2)]

(a) If the measured value that was set with the alarm 2 item goes below the lower limit and the

situation continues and remains for the alarm 2 delay time, CH1 alarm 2 flag (XnA) will

turn ON. At the same time, ALM2 LED flashes.

(b) If the measured value exceeds the lower limit, CH1 alarm 2 flag (XnA) will turn OFF. At

this time, ALM2 LED is turned off.

(c) If the measured value that was set with the alarm 2 item goes below the lower limit but

exceeds the lower limit within the alarm 2 delay time, then CH1 alarm 2 flag (XnA) will

remain in the OFF status.

(3) How to reset Alarm flag

1) When Alarm flag is ON during the alarm occurrence or the self-retention (in the case of the

alarm reset method = “self-retention“), Alarm flag can be reset (turned OFF) using Alarm

reset request.

2) How to reset Alarm flag during alarm occurrence (example of the upper limit alarm monitoring

with CH1 alarm 1)

(a) If the measured value that was set with the alarm 1 item exceeds the upper limit, CH1

alarm 1 flag (Xn9) will turn ON. At the same time, ALM1 LED flashes.

(b) By turning CH1 alarm 1 reset request (Yn9) to ON, CH1 alarm 1 flag (Xn9) will turn OFF.

At this time, ALM1 LED will remain flashing (because ALM1 LED is synchronized with the

alarm status, it will not turn off).

(c) Check that CH1 alarm 1 flag (Xn9) becomes OFF, and then set CH1 alarm 1 reset request

(Yn9) to OFF.

(d) If the measured value goes below the upper limit, ALM1 LED will turn off.

(e) After that, if the measured value exceeds the upper limit, CH1 alarm 1 flag (Xn9) will turn

ON again. At the same time, ALM1 LED flashes.

Figure 4.2.4-5 edure for resetting Alarm 1 flag (alarm reset method = “auto-reset”)

3) How to reset Alarm flag during self-retention (in the case the alarm reset method =

“self-retention” only)

Refer to the procedure described in (2) 1).

(4) Precautions during the alarm monitoring

1) When current demand time and electric power demand time are set to anytime except 0

second, current demand and electric power demand become lower than the actual values

(closer to 0) immediately after the power source ON and the CPU reset. When current

demand and electric power demand are being monitored for their lower limit, the alarm

occurrence flag may turn ON. Thus, to avoid this from happening, follow the procedure

below.

(a) Set the alarm monitoring target to “no monitoring” immediately after the power source ON

and the CPU reset.

(b) After passing for a 3-times longer period than the demand time, set the alarm monitoring

target again, and start the alarm monitoring.

4.2.5 Test function

This function is to output pseudo-fixed value to a buffer memory for debugging sequence program. The value can be output to the buffer memory without input of voltage and current.

(1) How to use the test function

1) Using the intelligent function module switch setting, you can start the test mode to output the

fixed value.

2) For procedure for the intelligent function module switch setting, refer to the following.

For GX Works2, refer to 8.6.2.

For GX Developer, refer to 8.7.2.

3) To finish the test mode, the set value is returned by the intelligent function module switch

setting, and after that, it enters to a measuring mode by resetting it.

(It resumes with the previous set value, electric energy and periodic electric energy.)

(2) Content of fixed-output

For the value to be output to the buffer memory, refer to Table 6.1-1 to 6.1-3 in 6.1 Buffer

memory assignment.

(3) LED display when using the test function

All LED lights.

(4) I/O signals when using the test function

Unit READY (Xn0) only ON. Other input and output signals are all OFF.

(5) Precautions for using the test function

Because fixed-output is output to the buffer memory, isolate the actual device to avoid

unexpected operation before running the sequence program.

computation is performed, this signal (Xn1) is turned ON and count of the output

period of data acquisition clock is started. After that, this signal turns ON at the timing

when the measurement data is completely written into the buffer memory after the

elapse of the output period of data acquisition clock.

If the settings of the input voltage, primary current, primary voltage of VT, secondary

voltage of VT, primary current of CT and output period of data acquisition clock are

changed, this signal turns ON immediately after the change of the settings and count of

the output period of data acquisition clock is started.

(b) This signal (Xn1) turns OFF 150 ms after it turns ON.

• When output period of data acquisition clock is 1 from 100, this signal (Xn1) turns

OFF 50 ms after it turns ON.

• When output period of data acquisition clock is 101 from 200, this signal (Xn1)

turns OFF 100 ms after it turns ON.

• When output period of data acquisition clock is more than 201, this signal (Xn1)

turns OFF 150 ms after it turns ON.

CH3: Un\G2000 to Un\G2099)

6.2.1 Phase wire system (Un\G0)

Phase wire system for target electric circuits is configured. This setting is common to all channels.

Do not change the set value from the default value of 4. Because this product is a three-phase

four-wire dedicated product.

6.2.2 Input voltage (Un\G1), Primary voltage of VT (Un\G5), Secondary voltage of VT (Un\G6)

Input voltage (Un\G1): set the Input voltage to the voltage transform module. This setting is common

to all channels.

Primary voltage of VT (Un\G5): when use for primary voltage of voltage transformer that is not in the

input voltage (Un\G1) setting, set the voltage of the primary side of

voltage transformer.

Secondary voltage of VT (Un\G6): when use for primary voltage of voltage transformer that is not in the

input voltage (Un\G1) setting, set the voltage of the secondary side of

voltage transformer.


(a) Set the Input voltage in the buffer memory. Setting range is as follows:

When set other than "101 to 116" the value of this setting, set to “0:any set” this setting, and

set primary / secondary voltage of VT (Un\G5 / Un\G6).

When the value of this setup is set as “101 to 116”, primary/ secondary voltage of VT are

disabled.

6.2.3 CH1 primary current (Un\G2), CH1 primary current of CT (Un\G7)

・CH1 primary current (Un\G2): set the primary current of the target electric circuit.

・CH1 primary current of CT (Un\G7): when use for primary

current of current transformer that is not in the CH1 primary

current (Un\G2) setting, set the current of the primary side of

current transformer. Secondary current of CT cannot be set.

Because secondary current of CT is fixed to 5A


(a) Set the primary current in the buffer memory. Setting range is as follows: Please choose the

settings to match the current sensor to be used.

When set other than "1 to 5, 501 to 536" the value of this setting, set to “0: any set” this setting,

and set primary current of CT (Un\G7).

When the value of this setup is set as “1 to 5, 501 to 536”, primary current of CT is disabled.

- Configurable range: 0 to 86400000 (ms)

*When the output period of data acquisition clock is set to 0, Data acquisition clock (Xn1) is

always OFF.

(b) Because the data update interval is 500 ms, Data acquisition clock (Xn1) runs every 500 ms.

Note that the output period of data acquisition clock is not a multiple of 500 ms, Data acquisition

clock turns ON at the time of the first data update after the elapse of the output period of data

acquisition clock.

<Example> When the output period of data acquisition clock is 1600 ms:

Measurement data update count = 1600 ms/500 ms = quotient 3 + remainder 100

ms.

Thus, the input device (Xn1) turns ON once in every four times the measurement

data is updated.

As a result, it is same as the case where the output period of data acquisition clock is

2000 ms.

(c) Turn Operating condition setting request (Yn2) from OFF to ON to enable the setting.

(2) Default value

It is set to 0 (ms).

・Data acquisition clock (Current measuring mode)

(a) Set output period of data acquisition clock (Un\G4000, 4001) in the buffer memory.

- Configurable range: 0 to 86400000 (ms)

*When the output period of data acquisition clock is set to 0, Data acquisition clock (Xn1) is

always OFF.

(b) Because the data update interval is 100 ms, Data acquisition clock (Xn1) runs every 100 ms.

Note that the output period of data acquisition clock is not a multiple of 100 ms, Data acquisition

clock turns ON at the time of the first data update after the elapse of the output period of data

acquisition clock.

<Example> When the output period of data acquisition clock is 250 ms:

Measurement data update count = 250 ms/100 ms = quotient 2 + remainder 50 ms

Thus, the input device (Xn1) turns ON once in every three times the measurement

data is updated.

As a result, it is same as the case where the output period of data acquisition clock is

300 ms.

(c) Turn Operating condition setting request (Yn2) from OFF to ON to enable the setting.

(2) Default value

It is set to 0 (ms).

10.2.4 If the electric current and voltage that are measured using this module do not match with the ones

measured with other gauge

Table 10.2.4-1 If current and voltage that are measured using this module do not match with the ones

measured with other gauge


Are primary current, and input

voltage correct?

Check the value in the buffer memory for checking

input current and primary voltage. When the value

in the buffer memory is changed, you need to turn

the request for operating condition setting into

ON. Otherwise, it will not be applied to the

measurement.

Section 6.1

Does the compared gauge measure

the effective value correctly?

This module stores the effective value into the

buffer memory. If the compared device uses the

average value instead of the effective value, the

resulted value may largely differ when there is

current distortion in the measurement circuit.

-

Is the secondary of CT

short-circuited?

Make sure that the secondary of CT is not

short-circuited. If it is connected to Mitsubishi’s

current transformer CW-5S(L), check that the

secondary switch is not short-circuited.

-

Are you using other current sensor

than recommended ones?

Only the dedicated current sensors can be

connected to this module. Check that other

company’s sensor is not being used.

-

Are you using the voltage transform

module?

Circuit voltage can not be entered directly into this

module. Enter the output voltage of the voltage

transform module (QE8WH4VT).

-

Do you connect the voltage transform

module has been done correctly?

Please check whether wiring of the is voltage

transform module performed correctly. -

10 - 6


10.3 Q&A

10.3.1 General

Q To what degree is the module durable against overvoltage and overcurrent? Is external

protective circuit required?

A

Momentary* : Up to 2 times as high as rated voltage and 20 times as high as rated current.

Continuous : Up to 1.1 times as high as rated voltage and rated current.

* Momentary means: Energizing 9 times for 0.5 seconds at 1-minute intervals, and then 1 time

for 5 seconds.

External protective circuit is not required.

Q Can the module be used as an electric energy meter?

A

This module can be used to measure the electric energy and to manage the use of electric

energy.

However, it cannot be used for deal and proof of electric energy measurement stipulated in the

measurement law.

Q Are errors in wiring verifiable easily?

A

They are verifiable by the illuminating condition of “MEA.,” “1,” “2,” and “3” LEDs on the front of

the module.

Refer to Section 10.2.3 for details.

Q Is it OK to open the secondary terminals of the current sensor?

A

The secondary side of the models EMU2-CT5-4W, EMU-CT50, EMU-CT100, EMU-CT250,

EMU-CT5-A, EMU-CT50-A, EMU-CT100-A, EMU-CT250-A, EMU-CT400-A, and EMU-CT600-A

is equipped with the protective circuit against opening of secondary terminals. Opening them

during the wiring work causes no problems. However, for safety, please do not continuously

energize the module with the terminals open.

The secondary side of the models EMU-CT400 and EMU-CT600 is equipped with the protective

circuit against opening of secondary terminals. However, during the wiring work, be sure to turn

the secondary side short-circuit switch to short. After completion of work, be sure to turn the

secondary short-circuit switch to open. Note that failing to turn the switch open results in an

inaccurate measurement.

Q Is measurement of inverter circuit possible?

A

Measuring the secondary side of the inverter is impossible due to the large fluctuation of

frequency.

Make measurement on the primary side of the inverter. However, since a current waveform on

the primary side of the inverter has a distortion containing the harmonic components, a slight

error occurs.

10 - 7


Q

If a load such as welding equipment exists, a current flows only for a short period (e.g.

2-cycle waveform of commercial frequency (50 Hz: 40 ms, 60 Hz: 33 ms)). Is accurate

measurement possible?

A

This module makes measurement with a sampling period of 4340 Hz (for both 50 Hz and

60 Hz). However, measuring part of buffer memory data (Un¥G100 to Un¥G2999) is updated

every 500 ms. The electrical amount such as current, voltage, electric power, power factor, and

frequency is measured in a cycle of 500 ms period.

It is impossible to measure the instantaneous short–term amount of electricity. The amount of

electricity and reactive power amount are measured separately from the momentary data

described above, using a sampling period of 4340 Hz continuously without intermittence.

Therefore, measuring the load for a short period is possible.

Q Obtained values may be different from other measuring instruments. Why is it so?

A

There are various possible causes. Check the following first, please:

[1] Check for wiring errors (polarity of current sensors, connections of current circuits, and

connections of voltage circuits, in particular).

[2] On the split-type current sensor, check for the poor engagement or separation of fitting

surfaces.

[3] On the split-type current sensor, check for pinching of foreign object between fitting surfaces.

[4] Check that the measuring instrument used for comparison indicates a correct RMS value.

[5] If the measuring instrument used for comparison measures an average value instead of rms

value, distortion in the current of the circuit to be measured causes a significant difference of

values. This module measures an rms value.

[6] Check for the short-circuit on the secondary side of the current transformer (CT).

[7] Current sensor connectable to the module is the dedicated current sensor only. Check that

the proper current sensor is connected or not.

10.3.2 Q&A about Specifications

Q What accuracy does “measuring accuracy” mean?

A

In terms of the amount of electricity, it means a range of tolerances in reading values. For

example, when the reading value is “10 kWh,” a tolerance is ±0.2 kWh.

In terms of measuring elements other than the amount of electricity, it means tolerance for the

rated input. For a current, when a rated current is set to 250 A, ±1% of 250 A is a tolerance.

Q Is accuracy of a current sensor and the voltage transform module included?

A

Accuracy of a current sensor and the voltage transform module are not included in accuracy of

the module.

A maximum value of tolerance is obtained by summing tolerance of the module and that of a

current sensor and the voltage transform module.

Q To what degree an area of microcurrent is measured?

A

A current value is measured from the area exceeding 0.4 % of the rated current. In an area

below 0.4 %, measurement result is indicated as “0” (zero).

However, in that case, still, the amount of electricity is being measured. Even if the indicated

value is “0,” measurement value will increase in continuing measurement for a long time.

The amount of electricity is measured with a load that is about 0.4 % or more of all load power.

10 - 8


Q What kind of time is “response time”?

A

“Response time” is a period of time between a point of sudden change of voltage or current

input and a point that an output (computation result) follows up to within± 10 % of input.

10.3.3 Q&A about Installing

Q What is wire diameter that allows installing a current sensor?

A

The nominal cross-sectional areas of the conductor of 600-V vinyl coated wires that can

penetrate (values for reference), refer to 8.5.3.1.

The above shows the standard nominal cross-sectional areas. Due to the outer difference of

finished vinyl insulation and deformation (bending) depending on manufacturers, a wire may

not penetrate.

Make verification on site.

Q What are the points when installing a current sensor?

A

Models EMU2-CT5-4W, EMU-CT*** and EMU-CT***-A are split-type. If split surfaces are not

engaged sufficiently or a foreign object exists between the split surfaces, adequate

performances are not obtained. Pay attention in installation.

10.3.4 Q&A about Connection

Q Does polarity exist in connection between a current sensor and the module?

A

Yes, it does.

Make connections so that secondary terminals of current sensor (k, l) and terminal symbols of

module agree with each other.

If polarity is incorrect, the current value is measurable, but the electric power and the electrical

energy can not be measured correctly.

Q Does polarity exist in connection between a voltage transform module and the module?

A

Yes, it does.

Make connections so that output terminals of voltage transform module (PA, PB, PC, PD) and

terminal symbols of module agree with each other.

If polarity is incorrect, the voltage value, the electric power and the electrical energy can not be

measured correctly.

Q Are there any key points in avoiding errors in wiring?

A

Check polarity of current sensor on the primary current side.

Power supply side of the circuit is indicated as “K,” and the load is indicated as “L.” An arrow

indicates the direction from K to L.

Check the current sensor and the module are connected correctly for the 1-side circuit, 2-side

circuit, and 3-side circuit.

Besides, check that voltage inputs for voltage transform module are connected correctly

among P1, P2, P3, and P0.

Q How do wires extend between a current sensor and the module?

A

Model EMU-CT***, EMU-CT***-A are extendable up to 50 m.

Model EMU2-CT5-4W is extendable up to 11 m, using together with extension cable. To extend

the wire further, use the current transformer CW-5S(L) for split-type instrument in combination,

extending the secondary wiring on CW-5S(L) side.

10.3.5 Q&A about Setting

Q Is the setting required?

A At least, settings of, primary current and input voltage are required. Specify settings in

accordance with a circuit to be connected.

Q If a primary current setting value is different from that of rated current on a connected

current sensor, does it cause a breakdown?

A It does not cause breakdown or burning. However, measurement values will be totally

incorrect.
